Manual orbital sander

Abstract

A hand-operated orbital sander ( 10 ) with a housing ( 12 ) on which a tool ( 18 ) capable of being moved in an oscillating manner is mounted, whereby the orbital path of the tool ( 18 ) is limited by longitudinal, elastic oscillating elements that couple the tool ( 18 ) with the housing ( 12 ), said hand-operated orbital sander being made more quiet-running by the fact that the oscillating elements ( 170, 180 ) comprise two tapered areas ( 50, 52 ), in particular constrictions, positioned far off-center at a distance from each other.

1. A hand-operated orbital sander ( 10 ) with a housing ( 12 ) on which a tool ( 18 ) capable of being moved in an oscillating manner is mounted, whereby the orbital path of the tool ( 18 ) is limited by longitudinal, elastic oscillating elements that couple the tool ( 18 ) with the housing ( 12 ), wherein the oscillating elements ( 170 ,  180 ) each comprises first and second tapered areas ( 50 ,  52 ) positioned at a distance from each other, wherein each of the first and second tapered areas is closely adjacent to an end of the oscillating element, wherein each of the first and second tapered areas of the oscillating elements ( 170 ,  180 ) is configured as two opposite, concave, recesses, wherein said recesses form a film hinge, wherein said film hinge has a bending resistance in a direction transverse to the recesses that is less than a bending resistance in a direction parallel to said recesses. 
   
   
     2. The hand-operated orbital sander according to  claim 1 , wherein each of the first and second tapered areas ( 50 ,  52 ) of the oscillating elements ( 170 ,  180 ) is configured as a circumferential constriction about the circumference of each oscillating element. 
   
   
     3. The hand-operated orbital sander according to  claim 1 , wherein each of the oscillating elements ( 170 ,  180 ) has a transverse leaf ( 55 ,  57 ,  59 ,  60 ).
